OLBERMANN: Obviously, you can bear personal witness to the top 10 signs that a presidency has crossed the line, and last time, you did mention a couple of things that wound up cutting through the partisanship of the equation. But is that possible now? Can anybody add anything that illuminates rather than just heats?

DEAN: Well, I think they can, in this regard. We're looking at something, really, that is a matter of process. There was a lot of debate, for example, during the Clinton impeachment about whether the wisdom or not appropriate nature of a censure.

And I think they missed the point, and I think somebody needs to bring some of this testimony forward to look at this in a broader context of what it's doing if the Congress doesn't stand up and say something about what the president is doing, in essence, we have, down in 1600 Pennsylvania Avenue, lawyers who are taking the most aggressive readings on any part of the law they can to enhance executive power.

And I think it's past time for Congress, really, to stand up and do something about it.
